On most dating apps, swiping right on a profile means sending a match request, while swiping left skips the profile. Once both users swipe right, they can start messaging each other. There’s a common belief that since most heterosexual dating apps have more men than women, the best strategy for men is to swipe right on every profile and see who matches. However, as a data scientist, I’d like to explain why this might not be the most effective approach.
